Comment(by aperi2007):

 I check better.
 Is possibile to use the LineStringSegment, but using a sub-part of what
 generated from ST_AsGML(3).
 Infact the structure is like this:

         <gml:TopoCurve>
           <gml:directedEdge>
             <gml:Edge gml:id="Edge_2_192278">
               <gml:directedNode orientation="-">
                 <gml:Node gml:id="Node_1_242975" />
               </gml:directedNode>
               <gml:directedNode>
                 <gml:Node gml:id="Node_1_243597" />
               </gml:directedNode>
               <gml:curveProperty>
                 <gml:Curve>
                   <gml:segments>
                     <gml:LineStringSegment>
                       <gml:posList srsDimension="2">...</gml:posList>
                     </gml:LineStringSegment>
                   </gml:segments>
                 </gml:Curve>
               </gml:curveProperty>
             </gml:Edge>
           </gml:directedEdge>
         </gml:TopoCurve>

 This version is better because allow even the description of multiparts
 repeating the LineStringSegments.
 Like this

         <gml:TopoCurve>
           <gml:directedEdge>
             <gml:Edge gml:id="Edge_2_192278">
               <gml:directedNode orientation="-">
                 <gml:Node gml:id="Node_1_242975" />
               </gml:directedNode>
               <gml:directedNode>
                 <gml:Node gml:id="Node_1_243597" />
               </gml:directedNode>
               <gml:curveProperty>
                 <gml:Curve>
                   <gml:segments>
                     <gml:LineStringSegment>
                       <gml:posList srsDimension="2">...</gml:posList>
                     </gml:LineStringSegment>
                     <gml:LineStringSegment>
                       <gml:posList srsDimension="2">...</gml:posList>
                     </gml:LineStringSegment>
                     <gml:LineStringSegment>
                       <gml:posList srsDimension="2">...</gml:posList>
                     </gml:LineStringSegment>
                   </gml:segments>
                 </gml:Curve>
               </gml:curveProperty>
             </gml:Edge>
           </gml:directedEdge>
         </gml:TopoCurve>
